1. An apparatus for testing tires at high speed comprising:

  • a rotatable wheel having an outer surface, means for supporting said wheel on a frame, and means for driving said wheel;

    a tire mounting means connected to a housing for rotatably mounting a test tire having an outer surface, and means for moving said housing and test tire toward and away from said wheel; and

    means for supporting said housing such that during movement of said test tire toward said wheel an acute angle is formed between the outer surface of said test tire and the outer surface of said wheel when the test tire initially engages the wheel, and said means for supporting said housing providing for a variable acute angle being formed between the outer surfaces of said wheel and test tire depending upon the diameter of the test tire;

    wherein said means for supporting said housing includes members which are connected between the frame and the housing and wherein said members are arranged in a nonparallel relationship with respect to each other;

    wherein said members, housing, and frame form a trapezoid; and

    wherein said members are connected to the housing and the frame by means of universal joints.
